Benefits of technology
[0017]Another objective of the present invention is to provide a skin care device adopting a power control means to effectively maintain a power supply and prevent the unnecessary consumption of energy. When the skin care device is switched on, only the main CPU is actuated until an additional control signal is received to operate the next step.
[0032]This supersonic skin care device is equipped with a sensing device (60) for detecting skin contact to automatically escalate the output of supersonic vibration. This supersonic skin care device is also equipped with a heat-sensing unit (70) for automatically shutting down power when it detects abnormal overheating, so that it is possible to protect the skin from burning.
Problems solved by technology
But the DC-DC converter is expensive and necessitates an increase in production cost.
Further, if the electric voltage is rapidly increased by the DC-DC converter, it causes an interruption in current in the skin care device, which wastes energy.
The second conventional skin care device has a disadvantage in that it wastes energy by distributing power to all of the components of the circuits and the CPU, activating even those components which do not need to be operated, by turning on the main switch.
Because this device uses several different voltages to operate grouped circuits inside the device, it is inconvenient for maintaining a consistent voltage.
Energy is wasted when transforming power supply voltages.
If the voltage is suddenly increased by the DC-DC converter to initiate the supersonic vibrator, it causes the device to power down momentarily due to an overflow of power.
Therefore, most present conventional skin care devices are limited in the amount of adjustment of the strength of vibration.
Thus, energy is wasted by unnecessarily idling the vibrating device.
It also does not provide a sensing device to sense whether the skin care device is contacting a users skin.
